Advantages of compound exhaust valves, models and applications of compound exhaust valves

The compound exhaust valve is reliable and can discharge a large amount of air in the pipeline and a small amount of gas in the operation of the system into the outside air at high speed. Easy to service, the composite exhaust valve can be easily removed from the system for maintenance, and the water in the system does not flow out, so there is no need to drain the system. Only exhaust, no drainage, steam and water separation disc design adopts a special structure to ensure that there is no drain during exhaust.

As long as the system is pressurized, the composite exhaust valve will continuously vent the air.

Exhaust valves are widely used in our daily life, but perhaps most people don't know much about what exactly it is. Or in what ways? Now I will give you a brief introduction to the relevant information of the composite exhaust valve.

The composite exhaust valve is a barrel-shaped valve body, which mainly contains a group of stainless steel balls, rods and plugs. There are many different models: CARX Composite Exhaust Valve, Composite Sewage Automatic Exhaust Valve, Composite High Speed Exhaust Valve, etc.

They can be widely used in different pipe exhaust fields, such as heating systems: we often quietly see ** air conditioning, solar heating systems; For example, long-distance water transmission system, composite exhaust valve can achieve water hammer protection and so on. Here are some models and applications.

CARX Composite Exhaust Valve

Introduction:Pressure Range:; Nominal diameter 25-100mm; The material can be cast iron, cast steel, cast copper. It is used at the highest point of the pipeline or in the place where there is closed air, and the gas in the pipe is removed to dredge the pipeline and achieve normal operation.

Scope of application: This valve is installed at the outlet of the pump or in the water supply and distribution line, which is used to remove a large amount of air in the pipeline to improve the efficiency of the water pipe and pump, and once there is negative pressure in the pipe, this valve can quickly inhale air to save the damage caused by negative pressure in the line.

Composite sewage automatic exhaust valve SCAR DN50-300

Product Introduction:Pressure Environment: Normal Pressure; The nominal diameter is DN50-300mm; Operating Temperature:

Room temperature; The material can be carbon steel and cast iron. The principle is the same as that of the CARX composite exhaust valve, the valve body is heightened, the lever mechanism is slightly changed, and the control part is reduced, so that the dirt is only in the lower part of the valve body, and will not wrap around the upper exhaust part of the mechanism, which will not affect the exhaust and cause water leakage.

Scope of application: It is used in large-scale sewage pressure conveying pipeline, which is of great significance to the normal operation and safe operation of long-distance sewage conveying pipeline.

FGP4X composite high-speed exhaust valve

Product introduction: pressure range, nominal diameter is DN50-300mm, the material can be cast iron, cast steel, stainless steel.

The composite high-speed intake and exhaust valve is installed in places where high-speed intake and exhaust is possible, and can be used in water pipelines. When filling with water, the air in the pipeline is discharged at high speed, and the air is inhaled when the pipeline is vented to keep the drainage smooth, and the precipitated air can be continuously discharged when the pipeline is working normally. When water hammer is possible, the air will automatically enter to avoid negative pressure and prevent or slow down the harm of water hammer.

The advantages of the compound exhaust valve are: reliable performance, easy maintenance, only exhaust, no drainage, under the pressure of the system, the compound exhaust valve will be continuously exhausted, as long as there is pressure will be exhausted. It has a higher flow rate and better performance than ordinary exhaust valves.

With the development of long-distance water supply projects and large-scale water diversion projects in China, the application of composite exhaust valves is also more important. Many areas of daily life are essential, and many problems have been solved in practical applications.

When installing and dredging pipelines, the most indispensable device is the compound exhaust valve, which can effectively dredge the excess gas in the pipeline at the closed place of the pipeline, so that the pipeline is unblocked, so the composite exhaust valve is widely used in heating systems, boiler pipes, air conditioning, floor heating and solar energy heating systems and other pipeline exhaust systems. However, because there is a lot of gas accumulation in the pipeline, the installation of the compound exhaust valve needs to be very careful, and the following will focus on the installation elements and characteristics of the compound exhaust valve.

Elements of the installation of the composite exhaust valve:

1.Before installation, check and remove debris from the main body. Install a gate valve in front of the valve for the next installation and maintenance.

2.If the valve is installed in a shaded shaft, there should be enough space for the technician to adjust and maintain it.

3.If the exhaust valve is installed outdoors, please pay attention to the insulation of the valve to prevent the water in the valve from freezing or freezing the valve.

4.If the pipeline where the exhaust valve is located has frequent water cut-offs, it is recommended to install a buffer valve in front of the exhaust valve.

5.The composite exhaust valve used for pipeline exhaust should be installed at the top of the hot water circulation, where gas tends to accumulate.

6.In order to prevent impurities from falling into the exhaust hole, the air cap of the composite exhaust valve should be slightly loosened when used to facilitate exhaust. If the exhaust cap is a safety moisture-absorbing exhaust cap, it should be fully tightened.

7.The exhaust valve installed on the radiator should be in the direction of the exhaust vertically upward.

8.Composite exhaust valves cannot be installed in places where they are prone to freezing.

Features of the compound exhaust valve:

1.Reliable performance: The discharge device is generally made of PK-EP, which has the best performance and highest reliability compared to all known synthetic materials, and can withstand high temperatures much higher than the operating temperature of the exhaust valve.

2.Perfectly equipped: The optimized material used for the O-ring is EPDM, which ensures that the O-ring remains elastic and reliable even at high temperatures.

3.Good internal structure performance: The internal spring of the valve core of the exhaust valve is made of special material trace dust, and imported nickel-plated stainless steel is used, which can prevent the oxidation of the valve core and affect the movement of the valve core.

At the same time, the exhaust mechanism of the compound exhaust valve is very reliable, and each valve has passed the exhaust test and pressure sealing test before leaving the factory. The individual components are cast with high precision, resulting in a perfect assembly.

4.Unique design: The design of the steam and water separation disc adopts a special structure to ensure that there is no drainage during exhaust.

Through the above introduction, you must also understand that in fact, the installation of composite exhaust valve is risky, during the installation process, the valve cap should always be open, otherwise the hot air or sewage squeezed in the pipeline will directly gush out due to pressure, causing unpredictable damage to people. At the same time, if the composite exhaust valve has a power outage in the heating system, the pipeline is ruptured, etc., it must be repaired immediately to check whether the entire pipeline is transported smoothly, so as not to cause greater losses.

The advantage of valve exhaust wheel core is that it can take into account low torque and high speed horsepower, and if you want to drive quietly, the valve exhaust can also be very quiet, the valve exhaust is a valve, the sound of opening the valve and closing the valve is different, some valves exhaust after closing the valve The exhaust sound is very small, so as to avoid disturbing the people.

In addition to sound, it also has an impact on engine performance, which is mainly used in turbocharged engines, because when the valve is closed, exhaust backpressure is generated, which can push the turbine to rotate more efficiently at low speeds, enhance the output of low torque performance, and also have a silent effect. When opened, the exhaust efficiency is improved, and the performance of the engine can be better played at medium and high speeds.

The working principle of automobile valve exhaust:

When braking, the engine exhaust pipe is closed with a valve, and the engine crankshaft is forced to carry out a rotational movement; During compression and exhaust stroke, the air is compressed in the cylinder, which increases the piston exhaust resistance, and achieves the purpose of reducing the vehicle speed through the drive train. At the same time as closing the exhaust pipe channel, cut off the fuel**, so the use of this kind of braking on long slopes can not only reduce the speed safely, but also save fuel.

In addition, when driving on icy and ice roads, the brake can be used to prevent the car from skidding. Exhaust brakes are mostly installed on diesel vehicles, because when the diesel engine is working in a braking state, it is easy to stop the fuel**. There are generally two types of exhaust brakes:

The electric type using the solenoid valve and the vacuum type using the vacuum cylinder.

The difference between the successful valve compound exhaust valve and the flanged exhaust valve is mainly in the following aspects:

The structure is different: the successful valve composite exhaust valve is composed of the valve body, bonnet, spool and spring spring, while the flanged exhaust valve is composed of the valve body, bonnet, valve and flange and other components.

Different occasions for application: Successful valve compound exhaust valve is suitable for high-rise buildings, underground pipelines, air conditioning systems and other occasions that need to be exhausted, while flanged exhaust valve is suitable for exhaust work of various pipeline systems.

The exhaust effect is different: the composite exhaust valve of the successful valve adopts a composite structure design, which can effectively remove the gas in the pipeline, while the exhaust effect of the flanged exhaust valve is relatively weak.

The installation method is different: the successful valve compound exhaust valve generally needs to be installed at the high point of the pipe, while the flanged exhaust valve can be installed in any position.

The service life is different: the service life of the successful valve compound exhaust valve is relatively long, which can reach more than 10 years, while the service life of the flanged exhaust valve is generally 5 years.

To sum up, although the successful valve composite exhaust valve and flanged exhaust valve are both exhaust valves, there are great differences in their structure, application occasions, exhaust effect, installation method and service life.

To put it simply, the way of exhaust is different, depending on whether you want to use it in the first regret shirt, the composite exhaust valve is the most commonly used exhaust valve in China, it is combined and improved on the basis of the group cavity float and float lever exhaust valve, and the performance of the successful valve can be installed well and more conveniently.
